To all whom it may concern.-

Be it known that I, CHESTER J. HoLMEs, of Stafford Springs, in the county of Tolland and State of Connecticut, have invented certain new and useful Improvements in \Vindow- Sashes, of which the following is a specification, reference being had to the accompanying drawings and the letters of reference marked thereon, where- Figure lis a view in vertical section through a window-frame, sash, and connected parts on a plane passing through the center of the guides. Fig. 2 is a view in vertical cross-section through the frame and sash, looking toward the side of the frame, showing the guide in plan View. Fig. 3 is a detail cross-sectional view of part of the sash, the guide, and the slide, to show construction. Fig. 4 is a detail face view of one of the guides in its groove.

The object of my invention is to provide a window-sash that shall be free to slide up and down in the usual manner in the frame, and that shall be so constructed and held as to be substantially airtight under extreme changes of weather, and shall also prevent the entrance of dust and stop all rattle.

My improvements to this end consist in combining with the window-frame a troughshaped metallic guide and placing in a groove along the edge of the sash a slide that is borne upon a spring which presses outward against the track or guide.

In the accompanying drawings, the letter a denotes a window-frame of ordinary construc tion; I), the upper sash, and 0 the lower sash, each balanced by weights 6, attached to the saslreords f, the latter being fastened to the sash in the ordinary manner. Each sash is provided with ways or guides g, secured to the jamb of the window upon the opposite vertapered so as to fit in the trough, but strike the bottom of the trough, and this construction prevents the parts from becoming loose by wear. These guides are secured to the windowan1b upon each side of the sash with the open face outward, and on one side of each groove in the sash a strip, h, of elastic material, as rubber, is fastened and pressed closely against the guide. I prefer to fasten each slide (1 upon the center of a leaf-spring, t, that is secured to the bottom of the groove by its opposite ends in such manner that one end of the spring is left free to slide, so that the spring, which in its normal shape is bent out ward at the center, may operate. The function of the spring-actuated slide is to thrust outward, so as to prevent the window from rattling sidewise, and these parts (the guide and slide) are what support the sash in its travel. The elastic strip or packing along the side of the groove and the side of the guide not only serves to exclude dust and air, but also to prevent in some degree the rattling of the window, although its chief use is to eX- elude dust. In case where the sash and glazing are of only moderate weight the friction caused by the outward thrust of the slide against the trough and the frictional grasp of the packing against the side of the trough will serve to hold the window in any desired part of its play without the need of using balancing-weights. A special advantage resides in the use of a metallic guide in this combination, for the reason that no changes of the weather can affect the lit of the parts so that they will stick or jam. The sash, having been once placed in easy running condition, will keep in serviceable shape for a long period.

I claim as my invention- 1. In combination with a windowsash or frame, a metallic trough-shaped guide fast to the frame, a sash having lateral grooves, each groove bearin g a spring-seated slide, and within the groove an elastic cushion between the side of the groove and the side of the guide, all substantially as described.

2. In combination, a window-frame having a trouglrshaped metallic guide, and a sliding sash with lateral grooves,and bearing a springseated slide pressed into the hollow of the ICO trough-shaped guide entering thegroove, and I0 as described. an elastic packing, also located in the groove 3. In combination with a Window-frame and between the side of the groove and the and a sliding sash, a metallic trough-shaped guide, all substantially as described,

guide by means of a spring, all substantially guide fast to the frame and a slide borne on i the sash and moving in the hollow of the (JHESTEF' HOLMES guide, all substantially as described. Witnesses:
